A metal oxide contains 40% oxygen by weight find its equivalentweight

Answers

Answered by jitendudip9j0vr

Assume the oxide has the formula \ce{MO}. Let the atomic weight of \ce{M} be x Then \frac{16}{x + 16} = \frac{40}{100} Simplifying and solving for x yields x = 24 Thus the metal is magnesium and the equivalent weight is 12.
